    Tuberculosis could be eradicated. So why isn’t it?

    Everything Is Tuberculosis
    John Green
    Crash Course Books, $28

    A few years ago, renowned author John Green met a boy named Henry at Lakka Government Hospital in Sierra Leone. Henry was small and, at first glance, looked about 9 years old to Green. Everyone at the hospital seemed to know and love him, making Green believe he was the child of a health care worker. That is until staff revealed that Henry was a patient with multidrug-resistant tuberculosis — and that he was…

  • Study confirms accuracy of blood test for early Alzheimer’s detection in Asian populations

    Study confirms accuracy of blood test for early Alzheimer’s detection in Asian populations

    A study in Alzheimer’s & Dementia, a leading journal in dementia research, has demonstrated the high accuracy of plasma p-tau217 as a blood-based biomarker for detecting abnormal brain beta-amyloid (Aβ) pathology, a hallmark of Alzheimer’s disease (AD). More significantly, the study validates its effectiveness even in individuals with cerebrovascular disease (CeVD), which is highly prevalent in Asian populations. This finding can enhance early diagnosis, improve patient risk stratification,…

  • New IVF method mimics fallopian tube environment, increasing sperm viability

    New IVF method mimics fallopian tube environment, increasing sperm viability

    The success of in vitro fertilization depends on many factors, one of which is sperm viability. A recent study from the University of Illinois Urbana-Champaign documents a new way to select viable sperm and prolong their viability in the laboratory, reducing one source of variability during the process.

    “The fallopian tube in women, or the oviduct, has an ability to lengthen sperm lifespan that, until now, we couldn’t recreate in IVF. In 2020, we discovered that complex sugars called glycans…

  • At-home smell test for early detection of Alzheimer’s disease

    At-home smell test for early detection of Alzheimer’s disease

    When it comes to early detection of cognitive impairment, a new study suggests that the nose knows. Researchers from Mass General Brigham developed olfactory tests — in which participants sniff odor labels that have been placed on a card — to assess people’s ability to discriminate, identify and remember odors. They found that participants could successfully take the test at home and that older adults with cognitive impairment scored lower on the test than cognitively normal adults….

  • The right moves to reign in fibrosis

    The right moves to reign in fibrosis

    The cells in human bodies are subject to both chemical and mechanical forces. But up until recently, scientists have not understood much about how to manipulate the mechanical side of that equation. That’s about to change.

    “This is a major breakthrough in our ability to be able to control the cells that drive fibrosis,” according to Guy Genin, the Harold and Kathleen Faught Professor of Mechanical Engineering in the McKelvey School of Engineering at Washington University in St. Louis,…

  • Healthy eating in midlife linked to overall healthy aging

    Healthy eating in midlife linked to overall healthy aging

    Maintaining a healthy diet rich in plant-based foods, with low to moderate intake of healthy animal-based foods and lower intake of ultra-processed foods, was linked to a higher likelihood of healthy aging — defined as reaching age 70 free of major chronic diseases and with cognitive, physical, and mental health maintained, according to a new study by researchers at Harvard T.H. Chan School of Public Health, University of Copenhagen, and University of Montreal. The study is among the first…

  • New non-surgical contraceptive implant is delivered through tiny needles

    New non-surgical contraceptive implant is delivered through tiny needles

    Mass General Brigham and MIT investigators have developed a long-acting contraceptive implant that can be delivered through tiny needles to minimize patient discomfort and increase the likelihood of medication use.

    Their findings in preclinical models provide the technological basis to develop self-administrable contraceptive shots that could mimic the long-term drug release of surgically implanted devices.

    The new approach, which would reduce how often patients need to inject themselves and…

  • Avoidable deaths are on the rise in the United States, yet falling in many peer nations

    Avoidable deaths are on the rise in the United States, yet falling in many peer nations

    When a person dies, clinicians often look at the cause of death to determine whether it could have been avoided, either by medical prevention such as vaccines or by treatments like antibiotics. These types of deaths are known as avoidable mortalities, and in most high-income countries around the world, the number is going down.

    But in the United States, avoidable deaths have been on the rise for more than a decade, according to a new study by researchers at the Brown University School of…

    Cats Are Getting Bird Flu. Here’s How To Protect Them

    The bird flu that is driving up the cost of eggs is also infecting cats, so cat lovers should take steps to protect them.

    The current strain of bird flu — avian influenza type A (H5N1) — is “quite serious” for cats, according to Julie Levy, DVM, Ph.D., DACVIM, a professor of shelter medicine education at the University of Florida.

    “This new version that is connected with dairy cows is…

  • Engineers develop a better way to deliver long-lasting drugs

    Engineers develop a better way to deliver long-lasting drugs

    MIT engineers have devised a new way to deliver certain drugs in higher doses with less pain, by injecting them as a suspension of tiny crystals. Once under the skin, the crystals assemble into a drug “depot” that could last for months or years, eliminating the need for frequent drug injections.

    This approach could prove useful for delivering long-lasting contraceptives or other drugs that need to be given for extended periods of time. Because the drugs are dispersed in a suspension before…
